Layer-1 Scaling Solutions In the decentralized ecosystem, a Layer-1 network refers to a blockchain, while a Layer-2 protocol is a third-party integration that can be used in conjunction with a Layer-1 blockchain . Bitcoin, Litecoin, and Ethereum, for example, are Layer-1 blockchains.

An independent blockchain acting in concert with Bitcoin or Ethereum , which retroactively became known as a “Layer 1 chain” or “main chain.” Layer 2 chains process new transactions faster while reducing the load on Layer 1 and typically taking much lower fees.

What Is Bitcoin Layer 3? Layer 3 is often referred to as the application layer. It is a layer that hosts DApps and the protocols that enable the apps . While some blockchains such as Ethereum or Solana (SOL) have a thriving variety of layer 3 apps, Bitcoin is not optimized to host such applications.
